This bindist tarball was built on 9.3-RELEASE. But it can be used on the latest releases of the 10.x and 11.x branches as well — that is, it works on 9.3-RELEASE, 10.3-RELEASE, and 11.0-RELEASE. It may work on 12-CURRENT, but your milage may vary.
In order to be able to install the contents, the following ports or packages should be present on the system:
devel/gmake (GNU make)lang/perl5 (Perl)lang/gcc (GCC 4.9 or later, including GMP and binutils)converters/libiconv (on all versions, despite that 10.x or later has iconv in base)configureAlthough GHC may work with Clang, it is recommended to use GCC from the Ports Collection until the Clang support receives more testing on FreeBSD.
$ env CC=gcc49 ./configure --with-ld=/usr/local/bin/ld --prefix=$PREFIXRegarding the LLVM-based code generator, note that the bindist was built with the LLVM tools present but recently the naming of the FreeBSD LLVM ports have changed, so their paths should be set manually in GHC's settings file (under lib/ghc-X.Y.Z) according to the version of LLVM installed. That is, llc37 and opt37 for LLVM 3.7 (installed via devel/llvm37), and so on.
After configure has completed successfully, just use GNU make(1):
$ gmake installPlease report problems directly to .
